Selectively fix & close open boundaries. In many cases after running Join (Automatic) you may discover that several troublesome boundaries still cannot be joined and closed, this is where Join Interactive is used.

Command Sequence
1. Select menu: Tools | Join Wizard | Join (Interactive)...
2. Choose the Tolerance and resulting layer for the joined objects. Then press OK.
Note: The Tolerance is used when join interactive attempts to join adjacent objects.
3. Select an object (ie. lines, arcs, traces) on the boundary you want to join.
Note: Join Interactive will now attempt to join adjacent objects to form the closed boundary. When there is a gap or multiple objects, Join Interactive will stop and prompt you to select the next object on the boundary.
Note: Join Interactive will also accept any coordinate point to select. This is handy when there is a big gap (or missing section) of a boundary.
Note: Join Interactive will also accept the following options:
End - Stop and create an open boundary.
Close - Stop and create closed polygon.
Back - Undo last object added to Join Interactive boundary
4. Once the boundary has been closed, it will be automatically converted to a polygon and placed on the output layer.
5. Repeat Steps 3-4.
